(Cl. 229-45) ABSTRACT F THE DISCLQSURE This disclosurerelates to a method of making cylindrical container bodies by providingan elongated rectangular fiat board means and applying lining means toone side thereof and label means to the other side thereof so that theboard means can be subsequently convolutely wound to provide a pluralityof cylindrical container bodies each having the lining means forming theentire interior surface thereof and the label means forming the entireexterior surface thereof, the flat board means having sealing meansdisposed thereon in transverse, parallel and spaced relation so thateach resulting container body will have an annular band of sealing meansat the opposed ends thereof to cooperate with end closures subsequentlyclosing the ends to provide a sealing means for such end closures.

This invention relates to an improved convolutely wound container or thelike as well as to improved board means for making such a container orthe like. In addition, this invention relates to an improved method ofmaking such a container or such a board means.

It is well known that various containers can be formed by convolutelywinding board means on a mandrel so that the individual container bodiescan be subsequently cut from the container body stock issuing from theend of the mandrel to have the open ends thereof subsequently closed bysuitable end closures after the container bodies have been filled with adesired product.

However, it has been found that no fully automatic and economical meanshave been provided for effecting a lluid sealing between the endclosures and the container bodies.

According to the teachings of this invention, however, improved meansare provided for automatically and economically providing a sealingmeans at the ends of the container bodies to be engaged by the endclosures closing the open ends of the container bodies to provide afluid seal therewith.

Accordingly, it is an object of this invention to provide an improvedcontainer having one or more of the novel features of this invention asset forth above or hereinafter shown or described.

Another object of this invention is to provide an improved board meansfor making such a container or the like.

A further object of this invention is to provide an improved method formaking such a container means or the like.

Another object of this invention is to provide an improved method formaking such a board means or the like.

Other objects, uses and advantages of this invention are apparent from areading of this description which proceeds with reference to theaccompanying drawings forming a part thereof and wherein:

FIGURE ll is a cross-sectional view taken on line 11- 11 of FIGURE 10.

While the various features of this invention are hereinafter describedand illustrated as being particularly adaptable to provide a convolutelywound container, it is to be understood that the various features ofthis invention can be utilized singly or in any combination thereof toprovide other devices as desired.

Therefore, this invention is not to be limited to only the embodimentsillustrated in the drawings, because the drawings are merely utilized toillustrate one of the wide variety of uses of this invention.

Referring now to FIGURE 1, an improved blank means for formingconvolutely wound container bodies is generally indicated by thereference numeral 20 and is fully illustrated in FIGURES 1-4.

The Ablank means 20 comprises a sheet of at cardboard-like means 21 forforming the container body structure of the containers of thisinvention. A strip of lining material, 22, such as metallic foil or alamination containing metallic foil is secured to the side 23 of theboard 21 in any suitable manner and has one end 24 thereof overlappingthe end 2S of the board 21 while the other end 26 thereof extendssubstantially slightly greater than one-half of the length of the board21, the foil side of the lining material 22 facing outwardly to providea moisture lbarrier against the product in a manner hereinafterdescribed.

A wrapper or label strip 27, such as aluminum foil or a laminationcontaining aluminum foil, is secured to the side 28 of the board 21 andhas an end 29 overlapping the end 30 of the board 21 while the other end31 of the wrapping material 27 extends slightly over one-half of thelength of the board means 21, the foil side of the lining materialfacing outwardly to provide a moisture barrier on the exterior surfaceof the resulting containers in a manner hereinafter described.

However, it is to be understood that the lining material 22, wrappingmaterial 27 and board 21 can be formed of other materials, as desired.

After the blank 20 has been formed in the manner previously described,sealing means, such as a hot melt wax-like material or the like isapplied in spa-ced parallel strips 32 on the label means 27 and inspaced parallel strips 33 on the liner means 22 in the patternillustrated in FIGURES 1-3.

After the sealing means 32 and 33 has hardened, the blank 20 illustratedin FIGURE 1 can be convolutely wound in a continuous manner on astationary mandrel in a manner well known in the art whereby the boardmeans 20 is convolutely wound upon itself so that the lining means 22will form the interior of the container body stock -and the wrappermeans 27 will form the exterior thereof, the convolutely wound boardmeans 20 being secured together by any suitable adhesive or the like ina conventional manner.

Thereafter, the convolutely wound container body stock issuing from theend of the stationary mandrel is automatically cut into a plurality ofcontainer bodies 34, FIG- URE 5, in a manner well known in the art,along the lines 35 illustrated in FIGURE 1 whereby the sealing means 32and 33 will be at each end of the container bodies 34.

Alternately, the blank means 20 illustrated in FIG- URE 1 can beseparated along lines 35 to provide the small blanks 20 illustrated inFIGURE 2 to individually form the convolutely wound container bodies 34.

In any event, the resulting container bodies 34 illustrated in FIGURE 5will each have the band means 32 and 33 of the sealing compound disposedat the opposed open ends 36 and 37 of the container body 34 in themanner illustrated in FIGURES 5 and 6.

In order to close the open ends 36 and 37 of the container body 34,after the same has been filled with the desired product, a suitable endclosure 38, FIGURE 7, is crimped over one of the ends 36 and 37 in themanner illustrated in FIGURE 7 whereby the curled bead 39 of the endclosure 38 fully engages the sealing means 32 and 33 to provide a fiuidseal therewith.

If desired, the sealing means 32 and 33 can be heat activated so thatduring the curling operation of the bead 39 of the end closure 38 withthe respective end 36 or 37 of the container body 34, the forming rollercan be heated to activate the sealing means 32 and 33 to further enhancethe sealing effect between the bead 39 and the end 36 or 37 of thecontainer body 34.

If desired, the end closure 33 can also contain sealing means 40 in themanner illustrated in FIGURE 8 to complement the sealing means 32 and 33carried by the container body 34 in the manner previously described.

Therefore, it can be seen that the blank 20 formed according to theteaching of this invention can be automatically convolutely wound on astationary mandrel or the like with the band means 32 and 33 of thesealing means so disposed thereon that as the resulting container bodystock issues from the stationary mandrel, the same can be cut intoindividual container bodies 34 along the lines 35 illustrated in FIGURE1 to produce the container bodies 34 having the sealing means 32 and 33at the opposed ends 36 and 37 thereof to provide the fluid-tight sealwith the end enclosures 38 subsequently utilized to close the open ends36 and 37 in the manner previously described.

If desired, the sealing means at the ends 36 and 37 of the containerbody 34 can be disposed only on the liner means 22 thereof if desired bymerely not placing the bands 32 on the blank 20 illustrated in FIGURE 1.

Also, the same sealing means which forms the bands 33 on the insides ofthe container body 34 can be part of an adhesive pattern placed on theblank 20 to secure together the overlapping portions of the convolutelywound board 20.

In particular, reference is made to FIGURES 9-11 wherein another blankmeans of this invention is generally indicated by the reference numeral41 and comprises the board means 21A previously described having thestrip of lining means 22A secured thereto and the strip 27A of Wrappingmaterial secured thereto in the manner previously described.

However, sealing means 42 is disposed on the board means 21A to providethe means for securing together the overlapping portions of theconvolutely wound blank 41, the sealing means 42 also defining the bands33A which Will subsequently provide the annular bands on the inside ofthe resulting container body in the same manner as the bands 33illustrated in FIGURE 5.

Therefore, it can be seen that the same sealing means utilized to securetogether the overlapping portions of the convolutely wound blank 41 willalso provide the sealing means for the end closures 38 subsequentlyutilized to close the open ends of the resulting container bodies.

Therefore, it can be seen that this invention has not only provided animproved blank or board means for forming a convolutely Wound container,but also this invention has provided an improved convolutely woundcontainer.

In addition, this invention has provided an improved method of makingsuch board means and/or container.
